Abstract

The present study describes the acetylation by an enzyme present in calf lens of a synthetic tridecapeptide [analogous to alpha-melanotropin (alpha-melanocyte stimulating hormone) but lacking the naturally occurring NH2-terminal acetyl group: des-Nalpha1-Ac-alpha-melanotropin]. The reaction is specific for the alpha-amino group of the NH2-terminal amino acid. The minimum length required for the substrate to become acetylated appears to be a sequence of five to eight amino acid residues. Modification of the internal lysine decreases the incorporation of acetate, irrespective of the size of the blocking group.
